Directories /etc and below are owned by root. Are you authenticated with root when upload the config?

You need to be root in order to edit or move anything in /etc/ as @RomeoNinov commented above , you could try to upload that config in your home directory first and later try to move using sudo mv

@RomeoNinov I'm accessing it using User - "ubuntu" is there any command which can help me grant the permission for this user so that i can update my apache2.conf directly from FTP

@ArpitMittal, copy the file to /var/tmp and then via command line move it to the proper place. Do not play with permission in /etc
